Microfluidic chip

Abstract

The invention provides a microfluidic chip, and belongs to the field of microfluidics. The microfluidic chip comprises a gas channel, a liquid channel, a mixing channel and a light-emitting area, one end of the gas channel is a gas inlet, one end of the liquid channel is a liquid inlet, the other end of the gas channel, the other end of the liquid channel and one end of the mixing channel converge at one position and are communicated with one another, and the other end of the mixing channel is communicated with one end of the light-emitting area. The other end of the light-emitting area is a gas-liquid mixing outlet, and the mixing channel comprises a plurality of groups of inverted S-shaped channels which are connected end to end. According to the microfluidic chip provided by the invention, gas enters the body channel, liquid enters the liquid channel, the gas channel and the liquid channel are communicated with the mixing channel at the same time and then enter the mixing channel to carry out mixing reaction, and a plurality of groups of inverted S-shaped channels which are sequentially connected end to end are arranged, so that the gas-liquid mixing time is longer, and the mixing is more sufficient; and the reaction is more complete, and the occupied area is small.

Description

technical field [0001] The invention relates to the field of microfluidic technology, in particular to a microfluidic chip. Background technique [0002] Microfluidic chip technology integrates the basic operation units such as sample preparation, reaction, separation, and detection in the process of biological, chemical, and medical analysis into a micron-scale chip to automatically complete the entire analysis process. Due to its great potential in the fields of biology, chemistry, and medicine, it has developed into a new research field interdisciplinary in biology, chemistry, medicine, fluid, electronics, materials, and machinery. [0003] The special micro-scale microchannels etched in the microfluidic chip can realize the uniform mixing reaction of the gas-liquid two-phase fluid, and facilitate the manipulation and control of the micro-scale fluid. Insufficient mixing of fluids results in insufficient gas-liquid reaction. Contents of the invention [0004] The inve...
